Abstract
We have performed Monte Carlo simulations to investigate the physics of heterojunction cathode Gunn oscillators. We show that a simple heterojunction cathode does not improve the device performance because the Gunn domain matures too quickly. The inclusion of a thin n+ layer at the heterojunction allows the Gunn domain to grow throughout the length of the device. This yields improved performance as was recently experimentally observed.
